BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates generally to a media player. More particularly, the present invention relates to improved features for connecting the media player to external devices.

2. Description of the Related Art

The hand held consumer electronics market is exploding, and an increasing number of those products are including mechanism for expanding connections thereto. By way of example, hand held consumer electronic products may correspond to cellular phones, personal digital assistants (PDAs), video games, radios, MP3 players, CD players, DVD players, televisions, game players, cameras, etc. Most of these devices include some sort of connector for making connections to other devices (e.g., Firewire, USB, audio out, video in, etc.). Some of these devices have been capable of connections to other devices through docking stations. For example, cellular phones have included docking stations for charging the cellular phones and PDAs have included docking stations for communicating with a host computer. Other devices have been capable of wireless connections therebetween. For example, cellular phones use wireless connections to communicate back and forth (e.g., include wireless receivers).

MP3 music players in particular have typically made connections to other devices through connectors. For example, the MP3 music player known as the Ipod manufactured by Apple Computer of Cupertino, Calif. has included a Firewire connector for communicating with a computer. The Firewire connector through a cable connected to the computer generally allows data transmissions to travel back and forth between the MP3 music player and the computer. As should be appreciated, MP3 music players are configured to play MP3 formatted songs. These songs may be uploaded from the computer and thereafter stored in the MP3 player. As is generally well known, the MP3 format is a compression system for digital music that helps reduce the size of a digitized song without hurting the sound quality, i.e., compress a CD-quality song without losing the CD sound quality. By way of example, a 32 MB song on a CD may compress down to about a 3 MB song using the MP3 format. This generally lets a user download a song in minutes rather than hours.

Although current media players such as MP3 music players work well, there is a continuing need for improved features for connecting or coupling media players to one or more external devices (e.g., input or output).

DETAILED DESCRIPTION OF THE INVENTION

The present invention will now be described in detail with reference to a few preferred embodiments thereof as illustrated in the accompanying drawings. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. It will be apparent, however, to one skilled in the art, that the present invention may be practiced without some or all of these specific details. In other instances, well known process steps have not been described in detail in order not to unnecessarily obscure the present invention.

FIG. 1 is a perspective diagram of a media player 100, in accordance with one embodiment of the present invention. The term “media player” generally refers to computing devices that are dedicated to processing media such as audio, video or other images, as for example, music players, game players, video players, video recorders, cameras, and the like. In some cases, the media players contain single functionality (e.g., a media player dedicated to playing music) and in other cases the media players contain multiple functionality (e.g., a media player that plays music, displays video, stores pictures and the like). In either case, these devices are generally portable so as to allow a user to listen to music, play games or video, record video or take pictures wherever the user travels.

In one embodiment, the media player is a handheld device that is sized for placement into a pocket of the user. By being pocket sized, the user does not have to directly carry the device and therefore the device can be taken almost anywhere the user travels (e.g., the user is not limited by carrying a large, bulky and often heavy device, as in a laptop or notebook computer). For example, in the case of a music player, a user may use the device while working out at the gym. In case of a camera, a user may use the device while mountain climbing. In the case of a game player, the user can use the device while traveling in a car. Furthermore, the device may be operated by the users hands, no reference surface such as a desktop is needed. In the illustrated embodiment, the media player 100 is a pocket sized hand held MP3 music player that allows a user to store a large collection of music (e.g., in some cases up to 4,000 CD-quality songs). Although used primarily for storing and playing music, the MP3 music player shown herein may also include additional functionality such as storing a calendar and phone lists, storing and playing games, storing photos and the like. In fact, in some cases, it may act as a highly transportable storage device.

By way of example, the MP3 music player may correspond to the Ipod MP3 player manufactured by Apple Computer of Cupertino, Calif. The pocket sized Ipod has a width of about 2.4 inches, a height of about 4 inches and depths ranging from about 0.72 to about 0.84 inches.

As shown in FIG. 1, the media player 100 includes a housing 102 that encloses internally various electrical components (including integrated circuit chips and other circuitry) to provide computing operations for the media player 100. In addition, the housing may also define the shape or form of the media player. That is, the contour of the housing 102 may embody the outward physical appearance of the media player 100. The integrated circuit chips and other circuitry contained within the housing may include a microprocessor (e.g., CPU), memory (e.g., ROM, RAM), a power supply (e.g., battery), a circuit board, a hard drive, other memory (e.g., flash) and/or various input/output (I/O) support circuitry. The electrical components may also include components for inputting or outputting music or sound such as a microphone, amplifier and a digital signal processor (DSP). The electrical components may also include components for capturing images such as image sensors (e.g., charge coupled device (CCD) or complimentary oxide semiconductor (CMOS)) or optics (e.g., lenses, splitters, filters). The electrical components may also include components for sending and receiving media (e.g., antenna, receiver, transmitter, transceiver, etc.).

In the illustrated embodiment, the media player 100 includes a hard drive thereby giving the media player massive storage capacity. For example, a 20 GB hard drive can store up to 4000 songs or about 266 hours of music. In contrast, flash-based media players on average store up to 128 MB, or about two hours, of music. The hard drive capacity may be widely varied (e.g., 5, 10, 20 MB, etc.). In addition to the hard drive, the media player 100 shown herein also includes a battery such as a rechargeable lithium polymer battery. These type of batteries are capable of offering about 10 hours of continuous playtime to the media player.

The media player 100 also includes a user interface 103. The user interface 103 allows the user of the media player 100 to initiate actions on the media player 100 and provides the user with output associated with using the media player (e.g., audio, video, images, etc.). The user interface 103 may be widely varied. By way of example, the user interface 103 may include switches; buttons, keys, dials, trackballs, joysticks, touch pads, touch screens, displays, microphones, speakers, cameras, and the like.

In the illustrated embodiment, the media player 100 includes a display screen 104 and related circuitry. The display screen 104 is used to display a graphical user interface as well as other information to the user (e.g., text, objects, graphics). By way of example, the display screen 104 may be a liquid crystal display (LCD). In one particular embodiment, the display screen corresponds to a 160-by-128-pixel high-resolution display, with a white LED backlight to give clear visibility in daylight as well as low-light conditions. As shown, the display screen 104 is visible to a user of the media player 100 through an opening 105 in the housing 102, and through a transparent wall 106 that is disposed in front of the opening 105. Although transparent, the transparent wall 106 may be considered part of the housing 102 since it helps to define the shape or form of the media player 100.

In addition to the display screen 104, the media player 100 also includes a touch pad 110. The touch pad is an intuitive interface that provides easy one-handed operation, i.e., lets a user interact with the media player with one or more fingers. The touch pad 110 is configured to provide one or more control functions for controlling various applications associated with the media player 100. For example, the touch initiated control function may be used to move an object or perform an action on the display screen 104 or to make selections or issue commands associated with operating the media player 100. In order to implement the touch initiated control function, the touch pad 110 may be arranged to receive input from a finger moving across the surface of the touch pad 110, from a finger holding a particular position on the touch pad and/or by a finger tapping on a particular position of the touch pad. The touch pad may be widely varied. For example, the touch pad may be a conventional touch pad based on a Cartesian coordinate system, or the touch pad may be a touch pad based on a Polar coordinate system. Furthermore, the touch pad 110 may be used in a relative and/or absolute mode. In absolute mode, the touch pad 110 reports the absolute coordinates of where it is being touched. For example x, y in the case of the Cartesian coordinate system or (r, θ) in the case of the Polar coordinate system. In relative mode, the touch pad 110 reports the direction and/or distance of change. For example, left/right, up/down, and the like.

The touch pad 110 generally consists of a touchable outer surface 111 for receiving a finger for manipulation on the touch pad 110. Although not shown in FIG. 1, beneath the touchable outer surface 111 is a sensor arrangement. The sensor arrangement includes a plurality of sensors that are configured to activate as the finger sits on, taps on or passes over them. In the simplest case, an electrical signal is produced each time the finger is positioned over a sensor. The number of signals in a given time frame may indicate location, direction, speed and acceleration of the finger on the touch pad, i.e., the more signals, the more the user moved his or her finger. In most cases, the signals are monitored by an electronic interface that converts the number, combination and frequency of the signals into location, direction, speed and acceleration information. This information may then be used by the media player 100 to perform the desired control function on the display screen 104.

The position of the display screen 104 and touch pad 110 relative to the housing 102 may be widely varied. For example, they may be placed at any external surface (e.g., top, side, front, or back) of the housing 102 that is accessible to a user during manipulation of the media player 100. In most cases, the touch sensitive surface 111 of the touch pad 110 is completely exposed to the user. In the illustrated embodiment, the touch pad 110 is located in a lower, front area of the housing 102. Furthermore, the touch pad 110 may be recessed below, level with, or extend above the surface of the housing 102. In the illustrated embodiment, the touch sensitive surface 111 of the touch pad 110 is substantially flush with the external surface of the housing 102.

The shape of the display screen 104 and the touch pad 110 may also be widely varied. For example, they may be circular, rectangular, triangular, and the like. In general, the outer perimeter of the shaped touch pad defines the working boundary of the touch pad. In the illustrated embodiment, the display screen is rectangular and the touch pad 110 is circular. More particularly, the touch pad is annular, i.e., shaped like or forming a ring. When annular, the inner and outer perimeter of the shaped touch pad defines the working boundary of the touch pad.

In addition to above, the media player 100 may also include one or more buttons 112. The buttons 112 are configured to provide one or more dedicated control functions for making selections or issuing commands associated with operating the media player 100. By way of example, in the case of an MP3 music player, the button functions may be associated with opening a menu, playing a song, fast forwarding a song, seeking through a menu and the like. In most cases, the button functions are implemented via a mechanical clicking action. The position of the buttons 112 relative to the touch pad 110 may be widely varied. For example, they may be adjacent one another or spaced apart. In the illustrated embodiment, the buttons 112 are configured to surround the inner and outer perimeter of the touch pad 110. In this manner, the buttons 112 may provide tangible surfaces that define the outer boundaries of the touch pad 110. As shown, there are four buttons 112A that surround the outer perimeter and one button 112B disposed in the center or middle of the touch pad 110. By way of example, the plurality of buttons 112 may consist of a menu button, play/stop button, forward seek button and a reverse seek button, and the like.

Moreover, the media player 100 may also include a hold switch 114. The hold switch 114 is configured to activate or deactivate the touch pad and/or buttons. This is generally done to prevent unwanted commands by the touch pad and/or buttons, as for example, when the media player is stored inside a user's pocket. When deactivated, signals from the buttons and/or touch pad are not sent or are disregarded by the media player. When activated, signals from the buttons and/or touch pad are sent and therefore received and processed by the media player.

The media player 100 may also include one or more connectors for receiving and transmitting data to and from the media player. By way of example, the media player may include one or more audio jacks, video jacks, data ports and the like. The media player 100 may also include one or more connectors for receiving and transmitting power to and from the media player 100.

In the illustrated embodiment, the media player includes a headphone jack 116 and a data port 118. The headphone jack 116 is capable of receiving a headphone or speaker plug associated with headphones/speakers configured for listening to sound being outputted by the media device 100. The data port 118, on the other hand, is capable of receiving a data plug/cable assembly configured for transmitting and receiving data to and from a host device such as a general purpose computer (e.g., desktop computer, portable computer). By way of example, the data port 118 may be used to upload or down load audio, video and other images to and from the media device 100. For example, the data port may be used to download songs and play lists, audio books, ebooks, photos, and the like into the storage mechanism of the media player.

The data port 118 may be widely varied. For example, the data port may be a PS/2 port, a serial port, a parallel port, network interface port, a USB port, a Firewire port and/or the like. In some cases, the data port 118 maybe a wireless link such as a radio frequency (RF) link or an optical infrared (IR) link in order to eliminate the need for a cable. Although not shown in FIG. 1, the media player 100 may also include a power port that receives a power plug/cable assembly configured for delivering powering to the media player 100. In some cases, the data port 118 may serve as both a data and power port.

Although only one data port is provided, it should be noted that this is not a limitation and that multiple data ports may be incorporated into the media player. In a similar vein, the data port may include multiple data functionality, i.e., integrating the functionality of multiple data ports into a single data port. Furthermore, it should be noted that the position of the hold switch, headphone jack and data port on the housing may be widely varied. That is, they are not limited to the positions shown in FIG. 1. They may be positioned almost anywhere on the housing (e.g., front, back, sides, top, bottom). For example, the data port may be positioned on the top, sides, back, front surfaces of the housing rather than the bottom surface as shown. Although it should be noted that having the data port on the bottom surface provides some benefits when connecting to other devices.

FIG. 2 is a diagram of a media player system 150, in accordance with one embodiment of the present invention. The media player system comprises a media player 152 and one or more media devices 154 that are connected via a media link 156. As mentioned above, the term “media player” generally refers to computing devices that are dedicated to processing media such as audio, video or other images, as for example, music players, game players, video players, video recorders, cameras, and the like. By way of example, the media player 152 may correspond to the media player 100 shown in FIG. 1. Media devices 154 are similar to the media player 152 in that they process media such as audio, video or other images. The media devices may be widely varied. By way of example, the media devices may correspond to other media players, desktop computers, notebook computers, personal digital assistants, video or imaging equipment (e.g., cameras, monitors), audio equipment (home stereos, car stereos, boom boxes), family radios (e.g., walkie talkies), peripheral devices (e.g., keyboards, mice, displays, printers, scanners), personal media devices (discussed in greater detail below) and the like.

The media devices 154 and the media player 152 are configured to communicate with one another through media link 156. The protocol under which they communicate may be widely varied. By way of example, the communication protocol may be a master/slave communication protocol, server/client communication protocol, peer/peer communication protocol, and the like. Using a master/slave communication protocol, one of the devices is a master and the other is a slave. The master controls the slave. Using a client/server communication protocol, a server program responds to requests from a client program. The server program may operate on the media player or the media device. Using a peer to peer communication protocol either of the two devices can initiate a communication session.

The media link 156 may be wired and/or wireless. For example, the media link 156 may be made through connectors and ports or through receivers, transmitters and/or transceivers. The media link may also be one way or two way. For example, in the case of one way, the media player may be configured to transmit signals to the media device but not to receive information from the media device (or vice versa) or in the case of two way, both the media player and media device may be enabled to receive and transmit signals therebetween. The signals may be data (analog, digital), power (AC, DC), and/or the like. In most cases, the data corresponds to data associated with the media player as for example audio, video, images and the like.

Both the media player 152 and the media device 154 include a media terminal 158A and 158B, respectively. The media terminals 158 may provide a direct connection between the media player 152 and the media device 154 (e.g., integrally formed with the media device) or it may provide an indirect connection between the media player 152 and the media device 154 (e.g., a stand alone device). The media terminals 158 provide the media link 156 through one or more connection interfaces. As such, the media player 152 may serve the media devices 154 and/or the media devices 154 may serve the media player 152. The connection interfaces associated with the media terminals 158 may be wired or wireless connection interfaces.

In wired connections, the media terminals 158 are configured to physically connect so as to operatively couple the media player 152 to the media device 154. For example, the media player 152 and the media device 154 may include a mating connection made up of connector and port. By way of example, the connection interface may include one or more of the following interfaces: PS/2, serial, parallel, network (e.g., Ethernet), USB, Firewire and/or the like. The connection interface may also include one or more remote, audio (digital or analog), video (digital or analog), and/or charging interfaces. In one embodiment, the media terminal 158B is a part of docking station that permits the media player 152 to connect with the media device 154. The docking station may be integrally formed with the media device 154 thereby providing a direction connection with the media player 152 or it may be a standalone device that provides an indirect connection between the media player 154 and the media device 152.

In wireless connections, the media terminals 158 do not physically connect. For example, the media player 152 and the media device 154 may include a receiver and transmitter for wireless communications therebetween. By way of example, the connection interface may include one or more of the following interfaces: FM, RF, Bluetooth, 802.11 UWB (ultra wide band), IR, magnetic link (induction) and/or the like.

In brief, FM (frequency modulation) is a method of impressing data onto an alternating-current (AC) wave by varying the instantaneous frequency of the wave. This scheme can be used with analog or digital data. RF generally refers to alternating current AC having characteristics such that, if the current is input to an antenna, an electromagnetic field is generated suitable for wireless broadcasting and/or communications. The frequencies associated with RF cover a wide range of the electromagnetic radiation spectrum as for example from about 9 kHz to thousands of GHz. Bluetooth generally refers to a computing and telecommunications industry specification that describes how mobile phones, computers and personal digital assistants can easily interconnect with each other using short range wireless connection. 802.11 generally refers to a family of specification for wireless local area networks (WLANs) developed by a working group of the Institute of Electrical and Electronics Engineers (IEEE). UWB refers to a wireless technology for transmitting large amounts of digital data over a wide spectrum of frequency bands with very low power for a short distance. IR generally refers wireless technologies that convey data through infrared radiation.

FIGS. 3 and 4 are diagrams of docking stations 170 and 172, respectively, in accordance with several embodiment of the present invention. The docking stations 170 and 172 are hardware components that include a set of connection interfaces that allow a media player 174 to communicate with other media devices (not shown) that are not usually taken along with the media player 174. That is, the docking stations 170 and 172 make available additional functionality that would not otherwise be achieved through the media player 174 and/or the other media devices. The docking stations 170 and 172 may be built into the media device (e.g., hard wired) or they may be stand-alone devices that are connected to the media device through a separate connection (e.g., cord). By way of example, the media player 174 may generally correspond to the media player shown in FIG. 1.

As shown, each of the docking stations includes a housing 178. The housings 178 are configured with a media bay 180 capable of receiving the media player 174 for direct or indirect connection to a media device. The media bay 180 includes a media bay opening 182 in the surface 184 of the housing 178. The media bay opening 182 is configured to physically receive the media player 174. In other words, the media player 174 can be inserted into the media bay opening 182. Once the media player 174 is inserted into the media bay opening 182 (as shown in FIGS. 3B and 4B), the functionality provided by a media device operatively coupled to the docking stations 170 and 172 becomes available for use by the media player 174. Additionally or alternatively, the functionality provided by the media player 174 may become available for use by the media device operatively coupled to the docking stations 170 and 172. In most cases, a connector 186 of the media player 174 couples to a corresponding connector 188 within the media bay 180 when the media player 174 is placed in the inserted position. The media player 180 essentially becomes a fixed location device when coupled to the docking stations 170 and 172 through the media bay 180 (unless the docking station happens to be in another mobile device). When the media player 174 is taken out, it becomes mobile again. As should be appreciated, the docking stations 172 and 174 let a user simultaneously enjoy expansion possibilities with the portability of a smaller device.

The media bays 180 of the docking stations 170 and 172 may be widely varied. In most cases, the media bay openings 182 are dimensioned to receive the media players 174. That is, the inner peripheral surfaces of the media bay openings 182 are sized to receive the outer peripheral surfaces of the media player 174 (allowing for some tolerances). In FIG. 3, the media bay 180 is configured to receive the back end of the media player 174 while in FIG. 4 the media bay 180 is configured to receive a bottom end of the media player 174. In either case, the connector 186 on the media player 174 is configured to connect with the connector 188 on the docking station 170 and 172 when the media player 174 is inserted in the media bay 180. The position of the inserted media player 174 relative to the housing 178 may be widely varied. For example, the media bay 180 may be configured to receive the entire media player 174 as shown in FIG. 3 or it may only be configured to receive a portion of the media player 174 as shown in FIG. 4.

The inserted media player 174 is typically retained within the media bay 180 until it is removed from the media bay 180 (e.g., doesn't slide out). For example, a retention mechanism such as a snap, a spring loaded latch or a magnet may be used to hold the media player 174 within the media bay opening 182. The media player 174 may also be held within the opening 182 by the force of the engaged connectors 186/188 or under its own weight (e.g., gravity). An ejection mechanism may additionally be used to release the media player 174 from the media bay 180 (e.g., to overcome any holding forces). In some cases (as shown in FIG. 3), the user interface 175 of the media player 174 is completely exposed to the user so that it is accessible to a user while inserted in the media bay 180. In cases such as these, the user interface 175 (e.g., front surface of the media player) may be recessed below, level with, or extend above the external surface of the housing 178. In the illustrated embodiment of FIG. 3, the front surface 190 of the media player 174 is substantially flush with the external surface 184 of the housing 178.

FIG. 5 is a block diagram of a media player/docking station system 200, in accordance with one embodiment of the present invention. The system 200 generally includes a media player 202 and a docking station 204. By way of example, the media player and docking station may correspond to the media player and docking station shown in FIGS. 3 and 4. As shown, the media player 202 includes a processor 206 (e.g., CPU or microprocessor) configured to execute instructions and to carry out operations associated with the media player 202. For example, using instructions retrieved for example from memory, the processor 206 may control the reception and manipulation of input and output data between components of the media player 202. In most cases, the processor 206 executes instruction under the control of an operating system or other software. The processor 206 can be a single-chip processor or can be implemented with multiple components.

In most cases, the processor 206 together with an operating system operates to execute computer code and produce and use data. The computer code and data may reside within a program storage block 208 that is operatively coupled to the processor 206. Program storage block 208 generally provides a place to hold data that is being used by the system 200. By way of example, the program storage block 208 may include Read-Only Memory (ROM), Random-Access Memory (RAM), hard disk drive, flash memory and/or the like. As is generally well known, RAM is used by the processor as a general storage area and as scratch-pad memory, and can also be used to store input data and processed data. ROM can be used to store instructions or program code followed by the processor as well as other data. Hard disk drives can be used to store various types of data and can permit fast access to large amounts of stored data. The computer code and data could also reside on a removable program medium and loaded or installed onto the computer system when needed.

In one embodiment, program storage block 208 is configured to store an audio program for controlling the distribution of audio in the media player 202. The audio program may contain song lists associated with songs also stored in the storage block 208. The songs may be accessed through a user interface 210 operatively coupled to the processor 206. The user interface 210 may include a display for visually displaying the song lists (as part of a GUI interface) and a touch pad or buttons for selecting a song to be played or reviewing and/or customizing the song lists, i.e., the user may quickly and conveniently review the lists and make changes or selections thereto.

The media player also includes an input/output (I/O) controller 212 that is operatively coupled to the processor 206. The (I/O) controller 212 may be integrated with the processor 206 or it may be a separate component as shown. The I/O controller 212 is generally configured to control interactions with one or more media devices 214 that can be coupled to the media player 202. The I/O controller 212 generally operates by exchanging data (and/or power) between the media player 202 and the media devices 214 that desire to communicate with the media player 202. In some cases, the media devices 214 may be connected to the I/O controller 212 through wired connections and in other cases the media devices 214 may be connected to the I/O controller 212 through wireless connections. In the illustrated embodiment, the media device 214 is capable of being connected to the I/O controller 212 through a wired connection.

The media player 202 also includes a connector 216 capable of connecting to a corresponding connector 218 located within the docking station 204. The docking station 204 is operatively coupled to the media device 214 through transfer circuitry 220. The transfer circuitry 220 may provide a direct or indirect link to the media device 214. For example, the transfer circuitry 220 may be hard wired to the media device 214 as for example when the docking station 204 is integrated with the media device 214 or it may be passively wired as through a cord that temporarily plugs into the media device 214.

The connector arrangement 216/218 used to connect the media player 202 and the docking station 204 may be widely varied. However, in the illustrated embodiment, the connector arrangement 216/218 includes both power and data contacts. The power contacts 222 of the media player 202 are operatively coupled to a battery 224 of the media player 202 and the data contacts 226 of the media player 202 are operatively coupled to the I/O controller 212. As should be appreciated, the power contacts 222A of the connector 216 are configured to engage the power contacts 222B of the connector 218 so as to provide operational or charging power to the media player 202, and the data contacts 226A of the connector 216 are configured to engage the data contacts 226B of the connector 218 so as to provide data transmissions to and from the media player 202. The data contacts may be widely varied. For example, they may be configured to provide one or more data transmitting functionalities including Firewire, USB, USB 2.0, Ethernet, and the like. The connectors may also include a variety of other contacts 230 for transmitting other types of data as for example remote control, video (in/out), audio (in/out), analog TV, and the like.

FIGS. 6A and 6B are diagrams of a connector assembly pin arrangement 235, in accordance with one embodiment of the present invention. As shown, the arrangement 235 includes a first connector 236 and a second connector 238. The connectors 236 and 238 may be placed in a media player, docking station, at the end of a cord or cable and/or the like. By way of example, the connectors 236 and 238 may generally correspond to the connectors 216/218 of FIG. 5. The first and second connectors 236 and 238 each include a housing 240 and 242 and a plurality of corresponding contacts 244 and 246 that when engaged operatively couple the connectors 236 and 238 together. The housing is generally formed from an insulating material such as plastic and the contacts are generally formed from an electrically conductive material such as a copper alloy. In the illustrated embodiment, the contacts 244 protrude from the housing 240 for insertion into corresponding contacts 246 that are recessed within the housing 242 (e.g., male-female connection). In some cases, the contacts 244 are configured to snugly fit into the contacts 246 so that the connectors are held together. Additionally or alternatively, the connectors 236 and 238 may include a locking means for locking the connectors together. For example, one of the connectors may include a latch that engages and disengages to and from a portion of the other connector. The configuration of the contacts may be widely varied (e.g., spacing, # of rows or columns, etc.). In the illustrated embodiment, the contacts are spaced apart in a single row. The connectors may be manufactured using a variety of techniques. By way of example, the connectors may be manufactured using techniques similar to those used by JAE of Japan.

The signals carried by the contacts may be widely varied. For example, a portion of the contacts may be dedicated to Firewire signals while another portion may be dedicated to USB signals. The contacts may also be used for grounds, charging, powering, protocols, accessory identification, audio, line-in, line-out, and the like. Additional contacts may be used for grounding the housing of the connector. The number of contacts may also be widely varied. The number generally depends on the signals needed to support the devices using the connectors. In one embodiment, some of the contacts are used to support Firewire while other contacts are used to support USB. In this embodiment, the minimum number of contacts corresponds to the number required to support these devices. In most cases, however, the number of contacts tends to be greater than this number (other signals are needed). In the illustrated embodiment, each of the connectors includes at least 30 contacts, including Firewire contacts, USB contacts, grounding contacts, powering contacts, reserved contacts and the like. An example of a pin count which may used can be seen in FIG. 6C. Although this pin count is shown, it should be noted that it is not a limitation and that any configuration of the functions described therein may be used.

FIGS. 7A-E are diagrams of a stand alone docking station 250, in accordance with one embodiment of the present invention. The stand alone docking station 250 allows a media player 252 to communicate with other media devices (not shown). By stand alone, it is meant that it is physically separated from but operatively connectable to the media device (rather than being integrated therewith). As shown, the docking station 250 includes a housing 254 that encloses internally various electrical and structural components and that defines the shape or form of the docking station 250. The shape of the housing may be widely varied. For example, it may be rectangular, circular, triangular, cubical, and the like. In the illustrated embodiment, the housing 254 has a rectangular shape. The housing 254 may be formed by one or more housing components. For example, as shown, the housing 254 may be made up of a top member 256 and a base member 258. The manner in which the members 256 and 258 are connected may be widely varied (e.g., screws, bolts, snaps, latch, etc.).

Within a top surface 260 of the housing as shown in FIGS. 7A, 7B and 7E there is provided a media bay opening 262 for physically receiving a bottom portion 264 of the media player 252. As shown, the media bay opening 262 has shape that coincides with the shape of the media player 252, i.e., the bottom portion 264 of the media player 252 may be inserted within the media bay opening 262. The depth of the opening 262 is generally configured to keep the user interface of the media player 252 exposed to the user. The opening 262 may be vertical or sloped. As shown in FIG. 7E, the opening 262 is sloped so that the media player 252 rests in a tilted position within the docking station 250. As should be appreciated, a tilted media player 252 is easier to use (e.g., more ergonomic). The slope may be widely varied. For example, it may tilt the media player 252 about 5 to about 25 degrees and more particularly about 15 degrees.

Inside the opening 262 there is provided a first connector 266 for engaging a corresponding connector disposed on the bottom surface of the media player 252. The first connector 266 is typically exposed through the housing 254 so that the media player connector can engage it. By way of example, the connector arrangement may correspond to the connector arrangement shown in FIG. 6. In the illustrated embodiment, the media player connector is a female port and the docking station connector 266 is a male plug. The plug is generally dimension for a tight fit within the port so as to secure the connection between the media player 252 and the docking station 250 (e.g., no interlock except for connector). The first connector 266 is generally sloped to a similar angle as the opening 262 so that engagement occurs between the first connector and the media player connector when the media player 252 is slid into the opening 262. As should be appreciated, the sides of the opening 262 serve as guides for placing the connectors in the correct engagement position.

The first connector 266 may be operatively coupled to one or more second connectors, each of which may be used to connect to some external device such as a media device, power plug and the like. In some cases, the information passing through the first connector 266 is directed to a single second connector while in other cases the information is split into multiple second connectors. For example, the contacts of a single connector 266 may be split into different connectors such as one or more data lines, power lines, audio lines and the like. The second connectors may be similar to the first connector or they may be different. Furthermore, multiple second connectors may be similar or they may be different from one another. The second connectors are also exposed through the housing. In some cases, the second connectors are indirectly coupled to the docking station 250. For example, they may be coupled to the docking station 250 through a cord or cable that is attached to the docking station 250. One end of the cord is coupled to the docking station 250 while the other end, which includes the second connector is free to be engaged with an external device. In other cases, the second connectors are directly coupled to the docking station 250. For example, they may be attached to a portion of the docking station 250 without using a cord or cable. In cases such as these, the second connectors are free to be engaged directly to an external device or they may be coupled through a removable cord or cable. Alternatively or additionally, the cord it self may be used to split information, i.e., a Y cord or cable.

The internal components of the docking station 250 can best seen in FIG. 7C. FIG. 7C shows the docking station 250 with the top member 256 of the housing 254 removed. As shown, the internal components include at least a first connector 266 and a second connector 268 (both of which may correspond to a connector arrangement shown in FIG. 6). The internal components may also include an audio out connector 270. The connectors 266-270 are connected via a flex cable 272. The connectors 266-270 are positioned on one or more printed circuit boards 274 that are attached to the base member 258 of the housing 254. The first connector 266 is located at a position that places it within the opening 262 of the housing 254 (as shown in FIG. 7B). The second connector 268 and the audio out connector 270 are located at positions that place them within openings 276 at the backside of the housing 254 for external connection therefrom (as shown in FIG. 7D). Also contained within the housing 254 is a ballast 278 enabling the docking station 250 to support the media player 252 when inserted therein. An EMI shield may also be placed over the flex cable 272 to provide shielding.

FIG. 8 is an illustration showing the docking station 250 of FIG. 7 in use, in accordance with one embodiment of the present invention. As shown, the docking station 250 is operatively coupled to a media device 280 through a cable 282, i.e., the first end of the cable 282 is engaged with the second connector 268 of the docking station 250 and the second end of the cable 282 is engaged with a connector positioned on the media device 280. Furthermore, the media player 252 is operatively coupled to the docking station 250 via the above mentioned connector arrangement, i.e., the media player 252 is positioned in the media bay opening 262 of the docking station 250 such that the connectors are engaged. Through these connections, the media player 252 may communicate with the media device 280, i.e., data and/or power may be passed therebetween. In the illustrated embodiment, the media player 252 is a music player and the media device 280 is a desktop computer. As such, the user, for example using the user interface on the media player 252, may upload or down load songs between the media player 252 and the desktop computer 280 via the docking station 250. When uploading and downloading are completed, the user may simply remove the media player 252 from the docking station 250 and walk away.

FIGS. 9A-9C are diagrams of cable adapters 300, 302 and 304, respectively, that may be used with the docking station 250 of FIG. 7, in accordance with several embodiments of the present invention. In all three figures, the cable adapters 300, 302 and 304 include a docking station connector 306. The docking station connector 306 is configured to be received by the second connector 268 of the docking station 250. Although this connector arrangement may be widely varied, in the illustrated embodiment, the connector arrangement corresponds to the connector arrangement shown in FIG. 6.

As shown in FIG. 9A, the cable adapter 300 includes a cable 308. The docking station connector 306 is disposed at one end of the cable 308 and a media device connector 310 is disposed at the other end of the cable 308. The media device connector 310 may be widely varied. For example, it may correspond to a power connector, a Firewire connector, a USB connector and the like. It may also correspond to a connector similar to the docking station connector. In the illustrated embodiment, the media device connector 310 is a Firewire connector. An example of a cable adapter 300 including a docking station connector 306 using the pin count of FIG. 6C and a media device connector 310 using a 6 pin Firewire is shown in FIG. 9D.

Referring to FIG. 9B, the cable adapter 302 includes a pair of cables 312 and 314. The docking station connector 306 is disposed at one end of the cables 312 and 314 and a plurality of media device connectors 316 are disposed at the other ends of the cables 312 and 314. Each of the media device connectors 312 and 314 may be widely varied. For example, they may correspond to a power connector, a Firewire connector, a USB connector and the like. In the illustrated embodiment, the first media device connector 316A is a power connector and the second media device connector 316B is a USB connector.

As shown in FIG. 9C, the cable adapter 304 is configured to be used with a car stereo. The cable adapter includes a cable 318. The docking station connector 306 is disposed at one end of the cable 318 and a media device connector 320 is disposed at the other end of the cable 318. In this particular embodiment, the media device connector 320 is in the form of a cassette for insertion into a cassette deck of the car stereo. The cable adapter 304 also includes a power adapter plug 322 configured for insertion into a car power jack (e.g., cigarette lighter). The power adapter plug 322 extends from the docking station connector 306. In order to use the cable adapter 304, the user simply places the power adapter plug 322 in the power jack (this supports the docking station as well as provides power therethrough for powering or charging the media player) and the media device connector 320 in the cassette deck of the car stereo. The user may then select a song to be played through the car stereo using the user interface of the media player.

Although the cable adapters are shown as separate components of the docking station, it should be noted that in some embodiments they may be integrated therewith. That is, instead of having a docking station connector, the ends of the cables may be attached to the docking station.

Referring to FIGS. 10-14, integrated docking stations will be described in greater detail. Like stand alone docking stations, the integrated docking stations allow a media player to communicate with other media devices. However, unlike the stand alone docking station, the integrated docking station is integrated with or built into the media device. As should be appreciated, the electrical and structural components of the integrated docking station are typically enclosed via the housing of the media device, i.e., the docking stations do not have their own housing. The housing of the media devices also typically defines the media bay in which the media player is placed for connectivity to the media device. That is, the media devices themselves include one or more media bays for receiving the media players. The media bays are typically externally accessible to the media players so that media players can be easily be inserted into or removed from the media bays. The media bays may be any of those previously described. The removability of the media players allows the media player to support a variety of different types of media devices in a flexible manner. By way of example, the media devices may correspond to desktop computers, notebook computers, home sound systems, car sound systems, portable sound systems, home theater systems, video projectors, displays, audio or video recording equipment, cameras (e.g., photos, video), telephones, and the like. They may also include peripheral computing devices such as scanners, printers, keyboards, and the like.

In one embodiment, the mobile radio 390 allows a media player 399 to act as a mobile broadcasting station. For example, the user may broadcast music from the media player 399 to other media devices in a local area or within a local network. The mobile radio 390 generally includes a base 394 that includes the radio broadcast components (e.g., antenna, transmitter, receiver, volume controls, squelch controls, frequency controls, etc.).

The docking station 392 is integrated within the base 394. The docking station 392 includes a media bay 398 that may be placed anywhere on the base, as for example, the sides, top, front, back or bottom surfaces. The media bay 398 may be configured to receive any surface of the media player 399 so long as a connection is made between the media player 399 and the docking station 392. For example, it may be configured to receive the back of the media player as shown in FIG. 3 or it may be configured to receive the bottom of the media player as shown in FIG. 4. In the illustrated embodiment, the media bay 398 is configured to receive the back side of the media player 399 so that the user interface is exposed to the user. As such, the user may select a song and thereafter broadcast it to other users in the network.

Although the mobile radio and media device are shown as separate devices, it should be noted that they may be integrated thus eliminating the need for a docking station. For example, the radio broadcasting components such as receivers, transmitters, microphones, speakers and the like may be built into the media player as for example the media player shown in FIG. 1. The radio broadcasting components may be widely varied. For example, they may be associated with technologies including FM, RF, Bluetooth, 802.11 UWB (ultra wide band), IR, magnetic link (induction) and/or the like.

FIG. 15 is a diagram of a wireless communication system 400, in accordance with one embodiment of the present invention. The wireless communication system 400 generally includes a media player 402 and one or more media devices 404. The media player 402 is configured to send media via a wireless communication link 406 to the media devices 404 and the media devices 404 are configured to receive the media sent by the media player 402 over the wireless communication link 406. The media player is essentially configured to act as a personal transmitting station so that the user can transmit media stored on the media player to other devices. In some cases, the media devices 404 may also send media to the media player 402 and the media player 402 may also receive media from the media devices 404. By way of example, the media may generally correspond to audio, video, images, text and the like.

In order to send and receive media, the players and devices 402 and 404 generally include a transmitter, a receiver or a transceiver as well as some sort of antenna. The media is generally sent via the transmitter and the media is generally received via the receiver. In one embodiment, the media player includes a transmitter while the media devices include a receiver (for one way communications). In another embodiment, both devices include a transceiver (for two way communications). The antenna may be fully contained within the players/devices 402 and 404 or they may extend outside the devices (as shown). By way of example, the wireless communication link may correspond to FM, RF, Bluetooth, 802.11, UWB (ultra wide band), IR (infrared), magnetic link (induction) and/or the like.

The media player 402 may be widely varied. In the illustrated embodiment, the media player corresponds to the media player shown in FIG. 1. The media devices 404 may also be widely varied. These devices generally depend on the type of media being sent by the media player 402. By way of example, the media devices 404 may generally correspond to a personal mobile radio 404A, a personal tuning device 404B, a personal display device 404C, and the like. Personal generally refers to the fact that these devices pertain to a particular user. In one embodiment, these devices are handheld devices that are sized for placement into a pocket of the user. By being pocket sized, the user does not have to directly carry the device and therefore the device can be taken almost anywhere the user travels.

Personal mobile radios 404A generally include a microphone and speaker (or audio jack) so as to allow voice communications. The mobile radios may be based on push to talk (PTT) whereby pressing a button opens the communication line from the mobile radio to the media player. The mobile radios typically include an antenna such as a rugged rubber duck that consists of a coiled up element encased in rubber. The mobile radios may also include a channel tuner for selecting which channel to receive and send information, and a volume control dial for adjusting the volume of the audio signal. The mobile radios may also include a small display showing the selected channel, received signal strength, output power and the like. Mobile radios are generally well known and will not be described in greater detail.

FIG. 17 is a flow diagram of a wireless transmission method 450, in accordance with one embodiment of the present invention. The method may be implemented by a media player, as for example the media player shown in FIG. 15 or 16. The method generally begins at block 452 where a media item is selected. This is generally accomplished by user operating the media player via the user interface of the media player. Depending on the application, the user may conveniently move through a list of media items and thereafter make a selection once the desired media item is found. In the case of music, the user may scroll through a list of songs until a desired song is found. In the case of images, the user may move through a proof sheet until a desired image is found.

Following block 452, the flow proceeds to block 454 where the remote recipients are selected. Remote recipients generally refer to other devices that are capable of receiving the selected media item from the media player. Selecting the remote recipients may include selecting a signal channel as for example in the case of a broadcast (e.g., FM) or selecting a desired address as for example in the case of a network connection (e.g., Bluetooth). In broadcasting, a media item is transmitted over airwaves for public reception by anyone with a receiver tuned to the right signal channel, i.e., the media item is cast or thrown in all directions at the same time. In networking, a media item is transmitted to one or more unique addresses, i.e., each media device has its own unique address. When utilizing broadcasting, the user may simply select a channel via the user interface of the media player. For example, the user of the media player may select FM 98.1 and therefore the user of the media device must select FM 98.1 in order to receive the media item. When utilizing networking, the user may select one or more addresses via the user interface of the media player. For example, the user may enter one or more unique address directly or the user may select one or more unique addresses from a preexisting group stored in the media player. In some cases, the unique addresses may be stored as a buddy list.

Following block 454, the flow proceeds to block 456 where the media item(s) is transmitted. The media item may be transmitted locally to the media player and/or it may be transmitted wirelessly to the remote recipient. In most cases, the media item is transmitted to both the media player as well as to the remote recipients.

The various aspects of the method described above can be used alone or in various combinations. The method is preferably implemented by a combination of hardware and software, but can also be implemented in hardware or software. The method can also be embodied as computer readable code on a computer readable medium. The computer readable medium is any data storage device that can store data which can thereafter be read by a computer system. Examples of the computer readable medium include read-only memory, random-access memory, hard drive, flash memory, CD-ROMs, DVDs, magnetic tape, optical data storage devices, and carrier waves.

FIG. 18 is an illustration showing a personal transmitting station 500 in use, in accordance with one embodiment of the present invention. By way of example, the personal transmitting station 500 may correspond to the media player shown in FIG. 1. The personal transmitting station 500 is wirelessly connected to one or more personal media devices 502 through one or more wireless links 504. These devices 500 and 502 are connected via a wireless communication signal such as any of those previously described.

Although the personal transmitting station 500 may be configured to transmit several types of data to the personal media devices 502, in the illustrated embodiment, the personal transmitting station 500 is configured to transmit audio data in the form of music 502 (e.g., the personal transmitting station includes MP3 functionality for example) to one or more personal media devices 502 acting as personal tuning devices. As such, the user of the personal transmitting station 500 can perform disc jockey functions, i.e., the user can determine what songs to be played on both the personal transmitting station 500 as well as the personal tuning devices 502.

In this particular illustration, a first skier 506 holds the personal transmitting station 500 while second, third and fourth skiers 508, 510 and 512 each hold personal tuning devices 502. As shown, the first skier 506 is located away from the second, third and fourth skiers 508, 510 and 512. The first skier 506 is located on a first hill 514, the second and third skiers 508 and 510 are located on a ski lift 516, and the fourth skier 502 is skiing down a second hill 518. As should be appreciated, all of these locations are within the broadcasting or networking range of the personal transmitting station 500.

The personal transmitting station 500 is configured to send a music signal to the personal tuning devices 502 held by the second, third and fourth skiers 508, 510 and 512 and the personal tuning devices 502 are configured to receive the music signal sent from the personal transmitting station 500. The first skier 506 can therefore effect changes to what is being listened to by the second, third and fourth skiers 508, 510 and 512 by simply selecting a different song to be played on the personal transmitting station 500 (even though he is in a different location than the rest of the skiers). For example, the first skier 506 may end a first song and select a second song to be played therefore causing the personal transmitting station 500 to send the second song to the personal tuning devices 502.

Both the personal transmitting station 500 as well as the personal tuning devices 502 include a means for outputting sound. For example, they may contain speakers or jacks for coupling to headphones. These devices may also include a means for adjusting the volume. For example, they may contain dials or buttons for increasing or decreasing the volume. In some cases, the personal tuning devices may include a means for making song requests, i.e., text messaging or voice communications.

While this invention has been described in terms of several preferred embodiments, there are alterations, permutations, and equivalents, which fall within the scope of this invention. For example, although the invention has been described in terms of an MP3 music player, it should be appreciated that certain features of the invention may also be applied to other types of media players such as video recorders, cameras, and the like. Furthermore, the MP3 music player described herein is not limited to the MP3 music format. Other audio formats such as MP3 VBR (variable bit rate), AIFF and WAV formats may be used. Moreover, certain aspects of the invention are not limited to handheld devices. For example, the touch pad may also be used in other computing devices such as a portable computer, personal digital assistants (PDA), cellular phones, and the like. The touch pad may also be used a stand alone input device that connects to a desktop or portable computer. It should also be noted that there are many alternative ways of implementing the methods and apparatuses of the present invention. For example, although the touch pad has been described in terms of being actuated by a finger, it should be noted that other objects may be used to actuate it in some cases. For example, a stylus or other object may be used in some configurations of the touch pad. It is therefore intended that the following appended claims be interpreted as including all such alterations, permutations, and equivalents as fall within the true spirit and scope of the present invention.
